Question

Which of the following relationships between the type of RNA and it’s function is NOT correct?

A. mRNA carries the genetic code of DNA out of the nucleus to the ribosome

B. tRNA brings the correct amino acids to the growing amino acid chain

C. tRNA contains an anticodon to compliment the mRNA codon

D. tRNA clamps down onto the mRNA strand, pulling the mRNA strand to be read

Answer 1

B

because tRNA read the information from the mRNA to make the amino acid.

Answer 2

D. tRNA clamps down onto the mRNA strand, pulling the mRNA strand to be read

Step-by-step explanation:

The mRNA is formed by process of transcription using DNA template strand and serves as template for protein synthesis. In this way, it carries the genetic information from nucleus to ribosomes which are site for protein synthesis. Function of tRNA is to read the mRNA codon and to carry the respective amino acid to the site of protein synthesis. The tRNA binds to mRNA through its anticodon which is complementary to the mRNA codon. The two ribosomal sub units clamp down onto mRNA and form the protein synthesis complex.
